2023 Tahoe Premier battery issue

[StephenPT]

so what had to be replaced on yours? My sister is having the same issue.

His problem ended up being the liftgate module.

Here’s a helpful document that you can follow to identify the parasitic draw.

Hello all! I am new to this forum. I am hoping someone can help me. I have a new 2023 Tahoe with less than 3000 miles. The battery keeps going dead. The dealership cannot find anything wrong with it. It’s been there three times and everything checks out. So, it seems that there is something at my house that is draining the battery. I park in a garage. I have moved my key fob to the other side of the house. When I walk by it to take my dog out it seems to wake up and makes a buzzing noise. I am at a complete loss as to what is going on. This is my 6th Tahoe and I have never had a problem with the battery draining. I drive it most every day so it’s not sitting unused. Does anyone have any ideas?

Hi, I have the same problem. Parked in garage. First time they said at the dealership it was the home link garage door opener in the overhead console. Had to replace the whole console 3 month wait. Battery still died after a week in the garage. Same noises when I walk by as you described. Back to the dealer last week. They kept the car one week. Here’s what the said was done.
-Flashed the body control modules with an update from GM
-Checked battery strength
-Changed power liftgate module due to a recent GM Bulletin to replace

Got it back yesterday, have not heard the noises yet. We will see how it does. I think (3) times returned is a lemon law buyback in my state (PA)
